onMouseOut()

Source:

Handles when the mouse leaves a layer

onMouseOver()

Source:

Handles when the mouse enters a layer

validateProjection(spatialReference) → {Boolean}

Source:

Determines if layer's spatial ref matches the given spatial ref. Mainly used to determine if a tile wont display on a map. Highly recommend only calling this after a layer's load event has happened.

Parameters:
Name Type Description
spatialReference Object

spatial reference to compare against.
Returns:

true if layer has same sr as input. false otherwise.

Type
Boolean

Parameters:
Name Type Description
layerClass Object

the ESRI api object for the layer
apiRef Object

object pointing to the geoApi. allows us to call other geoApi functions.

an optional pre-constructed layer
epsgLookup function

an optional lookup function for EPSG codes (see geoService for signature)
